The book will be a welcome treat for Prince fans, who are eagerly awaiting the release of a vault of unreleased tracks.

Prince was found dead at the mansion on April 21 last year, with court documents last week revealing the house was littered with prescription drugs given to him under his secret alias Peter Bravestrong.

Just six days before he died, Prince fell ill on a plane and made an emergency stop in Illinois as he was returning home from a gig in Atlanta.

First responders revived him with two doses of a drug that reverses the effects of an opioid overdose.
